Specification of Letters Patent.

Application filed April ao, i914. serial No. 833,276. i

To all whom t may concern:

Be it known that I, PrER P. HonvTH, a

j subject of the King of Hungary, residing at thereof for transferring life boats from the deck to a point of suspension above the water.

A further object is to provide a swinging track mounted adjacent the gunwales of a ship and shiftable outwardly thereof whileU affording a slidable mounting means for tackle suspended life boats.

A still further object is to provide pivoted supporting posts upon the opposite gunwales of a ship for mounting longitudinally positioned tracks whereby life boats may be suspended capable of sliding substantially the entire length of the ship while the oppo-` site tracks are in contact when projected, affording greater rigidity to the structure.

Vith these general objects in view and others that will appear as the nature of the invention is better understood, the saine consists in the novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views: Figure 1 is a top plan view of a ship showing one of the davit track rails closed and the opposite one in its open position. Fig. 2 is a side elevation of the same. Fig. 3 is a perspective view of a portion of-a davit post illustrating a track rail and life boat suspended therefrom, parts being broken away. Fig. l is a vertical sectional view taken through the davit post and the track rail. Fig. 5 is a detail view of the pivotal suspending connection between theldavit neck arm and the track rail, and Fig. 6 is a top plan view of the adjacent ends of two track rail sections. Referring more in detail to the drawings, it is designed to position a desirednumber of life boats 10 upon the ship 11 and supported upon the deck 12 thereof.

A plurality of tubular posts 13 are mounted spaced apart upon the ship deck and adjacent the opposite gunwales thereof, while each of said posts is provided with a rod 141 journaled therein and having a gooseneck or curved arni15 projecting from the top thereof. A track rail 16 substantially Lshaped in cross section conforming to the curvature of the adjacent gunwale is pivotally suspended on the free ends of said swinging arms 15 by means of terminal studs 17 upon saidarins projecting through perforations 18 in the top flange of the rails while the adjacentportion ofthe rail webs are' provided with a cut away portion 19 for the accommodation of the heads 20ofsaid studs. `The lever 21 is hinged as at 22 to an outwardly projecting lug23 upon theneck 15 and whereby the neck is swung rotatably upon the mounting post 13.

Tackle blocks 2a are mounted upon` the opposite base flanges 25 of the track rails 16 by means of the rollers 26carried by the said blocks while a life boat 27 is suspended by means of two bails 28 to the adjacent blocks 24E by means of cables 29 and pulleys 30.

Each of the track rails 16 is provided of a plurality of sections 31 and 32 which sections are secured together by means of the interengaging adjacent ends as disclosed in Fig. 6. By referring to the said ligure it vwill be noted that the top web of the rail end 31 is extended for seating upon a correspending cut away portion 33 of the adjacent end portion, while the end 32 is provided with a vertically positioned extension 34; receivable within a corresponding slot 35 of the end 31 and whereby said ends are iitted together and retained by means of a removable `bolt 36 which passes through the extension 84 and the inclosing portions of the web.

The normal position of the track rails and life boats is illustrated in Fig. `1 upon the starboard side of the ship as being in a closed position with the said track rail and life boat positioned substantially above the gunwale of the ship. The operating levers 21 being provided upon the arms 15 of as many of the supporting posts 13 as desired, it is only necessary to swing downwardly a lever 21 and to exert an outward pressure thereupon to force the adjacent track rail outward away from the ship and with the life boat suspended therefrom free of the side of the hull and where the same may be readily lowered into the water by the occupants of the boat regulating the descent by grasping the cable ends 37. lNhen the track rail is swung outward to the limit of its movement as disclosed on the larboard side of the ship in Fig. l, the life boat may be slidably moved along the track rail to any desired point of the ship and is prevented from leaving the track by means of blocks Olthereon, while a pin 38 is adapted for insertion through one or more of the posts 13 and the rods lil journaled therein for locking the track rails in either extreme position. The forward ends of the two track'rails are adapted to abut against each other when the rails are projected into the position for `operating the life boats.

l/Vhile the forms of the invention herein shown vand described are what are believed to bepreferable embodiments thereof, it is nevertheless to `be understood thaty minor changes may be made in the form, proportion and details of construction without departing-from the' spirit and scope of the invention as setl forth in the appended claims.

What is claimed as new is:-

1. The combination with a ship, of a pluvvrality of tubular posts mounted on the ships deck adjacent to the gunwales, a rod journaled in the upper portion of each of said ing turn levers carried by said arms, opposite track rails pivotally suspended from the arms at opposite sides of the ship, pulley blocks provided with rollers slidably mounted upon said rails, limiting stops secured to said rails, life boats adjustably suspended from said pulley blocks, and inter* locking ends forwardly positioned upon said rails adapted for abutting each other when the life boats are in their operative positions.

ln testimony whereof I aiix my signature in presence of two witnesses.

PETER P. HORVTH.
